To all whom it may concern:

Be it known that I, CHESTER CoMsToCK, a citizen of the United States,residing in Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Lubricators, of whichthe following is a specification.

This invention relates to the class of lubricators known as sight feed,in which the oil falls by drops from one portion to another through anintervening space, which space is provided with transparent windowspermitting observation of the drops in order to ascertain if thelubricator is feeding properly.

The lubricator is especially designed for use in connection withpressure devices, such as the cylinders of gas engines, or aircompressors wherein the pressure varies between wide limits as thepiston reciprocates.

The invention has for an object to provide an improved form of means forpermitting a drop feed and at the same time allowing an equalization ofpressure on the oil in the vessel, so that the regularity of the feedwill not be affected by the variation of pressure. And so that thenormal formation and precipitation of the successive drops is notaffected.

A further object is to provide in a device that lubricates mechanismhaving variable pressure, means for mixing with the lubricating oil, anon-fluid lubricant, such as graphite or mica.

In the accompanying drawings, Figure 1 is a vertical axial sectionthrough a lubricator embodying my invention. Fig. 2 is a transversesection on the line 2-2 of Fig. l. Fig, 3 is a vertical section throughthe deecting receptacle, taken at right angles to Fig. 1. Fig. 4

-is a plan view of the receptacle. Fig. 5 is a modification of the formshown in Fig. /1. Fig. 6 is a transverse section on the line 6 6 of Fig.5 and Fig. 7 is a transverse section on the line 7-7 of Fig. 5.

Referring now to the structure shown in Figs. 1, 2, 3 and 4, thereceptacle for the oil denoted generally by A, consists of a base member9 connected with a top member l0 by a shell 11. v inlet closed by a plug12, for filling with oil. The top is also provided with a cap member 13,securely fitting an opening therein. Connected with the base of thereceptacle A is a chambered member B. This member comprises av shell 14whose upper member is secured to a flange 15 projecting from the base 9.Two or more side openings 16 are provided in the member 'B which areclosed by a glass tube 17. The shell 14 thereby constitutes a tubularmember, having a threaded outlet 18 in its lower portion.

In the bottom member 9 of the receptacle is provided an outlet passage 8for the oil that is adjustably restricted by means of a needle valve 19screwing in a plug 20 in the bottom member. The passage 8 leads tothebore 21 of a nipple 22 that is screwed into the base as shown in Fig. 1.The nipple has a projecting portion 23 around The top is also providedwith an v the bore from which the oil passes by drops from thereceptacle, such flow being controlled by the needle valve. The nippleis provided with a canopy portion or deflecting plate 24 forming aprotection for the drop of oil falling from the extension 23, to preventits being blown sidewise by the gas passing to and from the cylinder ofthe engine. The fiuid under pressure, entering through the exit 18 intothe chambered memberB, finds access to the upper portion of thereceptacle A by means of a passage 25 in the base member 9 into whichleads a tube 26 extending up through the oilvessel and opening thereinadjacent its top. By this means the pressure on the oil is equalized,notwithstanding the varying pressure in the cylinder or other mechanismthat is lubricated. Suitable deflecting means .are also provided in thebottom portion of the chambered member B, whereby the pressure gas willnot come in direct contact with the drops being fed. A deflecting member29 is located in the outlet portion 18 of the member B, and comprises ashank portion 30 fitting into said outlet, with a4 flange portion 31around its upper end, forming a kind of receiving cup, that is invertical alinement with the projection 23 through which the oil falls bydrops.

The lower portion of the receiving member is provided with a verticalpassage 32, that extends part way into the member, and terminates in atransverse or lateral passage 33; which lateral passage opens into thechambered vessel, thereby providing an inlet passage for the pressuregas. The upper cup portion of the receiving vessel is provided with twooutlets which are arranged out of alinement with the transverse passage33 in the member. By this means upon the fluid pressure entering thepassage 32 it will pass laterally through the bore 33 and thence passupward around the flange of the receiving vessel, and out of the path ofthedrops falling onto the top of the member inside of the fiange. Whilethe drops falling on top of the member inside of the fiange will passdownward through the lateral openings 34 and 35. But as these are out ofalinement with, and preferably at right angles with the bore 33, the oilwill fall on the bottom of the chambered vessel and not be brought inimmediate contact with the iniiowing gas. When the influx of the gas hasceased, and the exhaust stroke begins the gas flowing out, will permitthe oil to pass around from the outlet portions 34 and 35 of the member,to the transverse bore l33 and thence pass outward through the bore 18.By this means it will be seen that the pressure gas will be admittedaround the liange 31 into the chambered vessel and it will pass upwarduntil it reaches the passage 25, in which course it must pass around oroutside of the canopy or deflecting plate 24. Therefore, the gas willnot pass upward at the middle portion of the vessel, and will notinterfere with the dropping of the oil. I

li desired `a casing o glass 3G may be provided, extending between thecanopy 24 and the flange 3l, as shown in Fig. 1. This will prevent anyinterierence of the inflowing gas, with the oil dropping from theprojection 23 onto the receiving member. But such member is notnecessary where oil alone is used as a lubricant. A plug 27 screws inthe bore 18 and forces the receiving` member -30 upward to secure theglass tube 36 between its Hang@ portion and the nipple 23. Its reducedbore acts to restrict the passage oi the gas therethrough In theconstruction shown the lubricator is provided with an additional vesselcontaining a non-fluid lubricant, such-as graphite. A vessel 40 isprovided with a tubular stem 41 screwing into a threaded socket 42 inthe bottom member 9. A passage 43 leads from the stem 41 into 'thepressure passage 25. This vessel extends upward into the cap member 13and is closed thereby at its top. A pressure tube 44 is secured in thestem 41 and extends upward terminating in the upper portion ol thevessel 40. By this means the gas under pressure entering the receptaclehas iree access into this vessel 40 at its upper portion. On thepressure stroke ol' the engine the gas will be orced into the vessel 40through the several passages, and the tube 44, and will mingle with thegraphite 45 contained in the vessel. On the exhaust stroke of theengine, the pressure being reduced, the gas will flow out ot this vesselthrough the said passages, which will have the effect oi carryingsuspended or floating portions of the graphite with it, down through thetubes 44 and 41 and the passage 43, into the stream of gas owing outthrough the passage 25. The graphite will be carried further down intothe bore 33, and at this portion will mix with the drops oi oil flowingtherethrough, and pass through the exit 32 of the receiving member. Bythis means at each exhaust stroke of the engine, when the oil is flowingout oi the lubricator, a quantity of the graphite will be brought downbeyond the sight feed ot the oil and will be mixed with the oil as itpasses out of the lubricator. Where this graphite mixing device is used,it is desirable to use the glass shield 36, so that the graphite willnot mix with the oil until the latter reaches the bottom oi thechambered vessel B.

ln Fig. 5 is shown a somewhat similar construction but in which asimpler iorm of oil reservoir is shown. ln this construction there is acap 51 connected with a base member 52 by a shell 53. The cap contains aplug 54 tor supplying the oil. A chambered member C, similar to themember B, is shown as comprising a shell 55 secured to a flange portion56 oi the base 7. The shell is provided with kside openings 57 that areclosed by a glass tube 58. The bottom oi the shell 55 is provided withan outlet member 59, which may be provided with a reducing plug 60secured therein. At`

the upper portion oi the chambered member C is provided a nipple 61,similar to the nipple 21. This nipple is tapped into the base member 52and has a boreV 63 registering with a bore 64 in the bottom member 52.And needle valve 65 serves to adjustably restrict the passage 64 tocontrol the outlet of the oil so that it will iall by dropslirom theextension 66. At the bottom of the chambered vessel G is provided areceiving member 67, whose construction is practically the same as thereceiving member 30, except that its lower portion sealer 68 is reduced,forming the shoulder by which the member is seated in-the reducedportion 69 oi the outlet of the member. The base portion 52 oi thereceptacle is provided with two passages 70 into which extend tubes 71whose upper end terminate adjacent the top of the receptacle. By thismeans the pressure fluid can pass to the upper portion of the receptacleabove the oil and equalize the pressure.
